Its island comp BBL is machined from a single piece of stainless steel, eliminating timing issues and the potential to come loose. The front sight is attached to the compensated BBL—making this the first ever barrel with a compensator in front of an island sight, reduces muzzle jump, and enables you to keep eyes on the front sight rather than the blast. The comp reduces recoil by 63%. Includes the STI RecoilMaster dual spring recoil system, effectively making this the flattest, smoothest shooting pistol on the market.
